One-to-Many Composite Collection Mapping

Use XML composite collection mappings to represent one-to-many relationships. Composite collection XML mappings can reference any class that has an EclipseLink descriptor. The attribute in the object mapped must implement either the Java Collection interface (for example, Vector or HashSet) or Map interface (for example, Hashtable or TreeMap). The CompositeCollectionMapping class allows a reference to the mapped class and the indexing type for that class.
